So far so good. I use these heavy strings for a short scale guitar, and they compensate very well, I can get the sound of the long scale tightness, with a shorter neck. I alse really like the sound of stainless steel, it really gives that extra punch that I want and need. I wonder what they would sound on a long-scale Warwick Corvette, will definitely try it!!
What I didn't like about it is the package. That nylon sack, with no separate bag for each of the strings? Hilarious, and unworthy.
So, overall, 4 stars :) Well worth the price!
